 Testing Your Installation
 -------------------------
 
-To test your installation, you can run some of the scripts in the ``examples`` folder or run the regression tests with ``testflo -v`` from the root directory.
-Some of the examples require you to have `cgnsUtilities <https://github.com/mdolab/cgnsutilities>`_ installed.
+To test your installation, you can run the regression tests.
+Running the tests requires additional dependencies.
+Check if you have these installed by running:
+
+.. prompt:: bash
+
+    pip install .[testing]
+
+Once you have the necessary dependencies, download the reference mesh files:
+
+.. prompt:: bash
+
+    ./reg_tests/ref/get-ref-files.sh
+
+Then, in the root directory, run:
+
+.. prompt:: bash
